JURGEN FRERIGHS, OF GILMAN, ILLINOIS- CHIMNEY-REGULATOR.

SPECIFICATION forming part Of Letters Patent N0. 517,919, dated April10, 1894. Application filed December 5, 1893. Serial No. 492,84 (Nomodel.)

To a whom it may concern.- I

Be it known that I, JURGEN FRERICHS, a citizen of the United States,residing at Gilman, in the county of Iroquois and State of Illinois,have invented certain new and useful Improvements in Chimney-Regulators, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in chimney draft regulators and itsobject is to provide a device of this kind which will be simple andcheap in construction and efficient in operation; and to these ends itconsists in the novel construction and combination of parts hereinafterfully described and specifically pointed out in the claim.

In the accompanying drawings, Figure 1 is a perspective view of achimney draftregulator constructed in accordance with my invention. Fig.2 is a similar view showing the interior construction the outer partsbeing shown by dotted lines.

In the said drawings, the reference letter A designates the flue box,which is shown asbeing rectangular in cross section, and of a sizecorresponding with the chimney to which it is to be applied. To the topof this flue box is secured a plate B, to the upper side of which issecured a conical pipe 0, through which the draft passes.

The letterD designates a vertical rod mounted in brackets d, d, securedto the upper and lower ends respectively,of the flue box. Above the pipe0, the rod D is provided with a vertically movable cone frustum E, whichacts as a draft deflector. Above said deflector E, is a funnel shapedhood or cover F, likewise vertically movable on said rod, and above thetop of this cover or hood is a bracket G, which consists of a metalplate having its ends bent at right-angles forming short parallel armsg,

pipe 0, and cut ofl the draft.

g, provided with apertures through which rod D loosely passes, so thatthe bracket is slidable thereon. The lower arm of the bracket is formedwith anextension g, with which is connected a rod K. This rod passesthrough a guide L, secured to plate B and extends to within a sufficientdistance of the ground where it can be conveniently reached and operatedby hand. The rod D at its upper end is provided with ahead H, to limitthe upward movement of bracket G.

The letter P designates a coiled spring encircling the rod D, its lowerendresting on the upper bracket 61 and its upper end supporting thedeflector E and hood F.

The draft will be in the direction of the arrows shown in Fig. 2 andshould the chimney take fire itcan be instantly extinguished by pullingdown on rod K, which causes the deflector E, to close the mouth of theconical After the fire is extinguished, rod K is released when thecoiled spring restores the parts to their original positions.

Having thus described my invention, what I claim is- In a draftregulator for chimneys, the combination with the flue box A, plate B,conical pipe 0 and vertical rod D, of the deflector E, loosely mountedon said rod, the hood or cover F, also loosely mounted on said rod, thecoiled spring encircling rod D and interposed between plate Banddeflector E, the'vertically slidable bracket G, and the rod K,substantially as described. I

In testimony whereof I affix my signature in presence of two witnesses.

JURGEN FRERIOHS.
